What about Jindalee's over-the-horizon radar system?
RELATED LINKS Australia's Jindalee Operational Radar Network (JORN) comprises three Over-The-Horizon Radar (OTHR) systems and forms part of a layered surveillance network providing coverage of Australia's northern approaches.
JORN provides wide area surveillance of Australia's northern approaches at ranges of 1000 to 3000 km from the radar sites, and is used to conduct air and maritime surveillance in support of Australia's national surveillance effort.
JORN was designed to detect air targets equivalent in size to a BAE Hawk-127 aircraft or larger, and objects on the surface of the water equivalent in size to an Armidale Class Patrol Boat or larger.
The extent of available JORN coverage and actual system performance is highly variable and principally dependent on the state of the ionosphere, environmental conditions and an object's size and construction.
The detection by JORN of small wooden vessels is highly improbable, given the typical size, construction and speed of such vessels.
